Originally used for a tool for screwing in objects. Ratchet refer to someone who is ignorant, uneducated, selfish, and destructive. These creatures are often seen as scum to a society. They act like a complete jackass thinking they are "all that". Most listen to rap music post 2012. Often seen wearing Beats or Jordans. It's catchphrase is the n-word. They are often destroying our youth. Their natural habitat is the outskirts where crime is high and so is poverty. Most of them spend money toward fashion instead of good food and a college tuition, so their nutritional value comes from fast food. Yes, they do make racial stereotypes seem true.

The term ratchet, from a derogatory sense of the term, stems from drug use. A "ratchet" in slang usually refers to someone who is "ghetto", unkept, and unable to keep steady work. It's particularly derogatory towards lower class women. However it's use first comes from deep drug addiction where "ratchet" refers to someone (more often a woman apparently) that got into the grips of drug addiction from a drug dealer. We all have seen the faces of meth and what drug addiction can do to the body and face. So that's where its roots come from. Ratchet then became popularized with the musical genre Trap, a kind of instrumental electronic music with influences from "dirty south" rap. So from the recesses of drug addiction to pop culture and morphed into people who just can't take care of themselves.
